Want to check the extension here too?

[scroggo, 2015/03/19 12:57:54]

I thought about it, but this case is different:
We already don't check to make sure it has an image extension, unlike when we're
reading directories.
This isn't tested by the bots - it's only for local testing if someone wants to
test an individual file. If they try to decode a file that's not an image (or at
least doesn't have an extension we support), I think that's okay.
